12 Claims.

The object of this invention is to make a new and improved type of loose leaf binder. Another object of the invention is to provide inthe binder an assembly bar that is hinged to the fback independent of either cover and another assembly bar that is loose and detachable.

Another object of the invention is to provide the hinge bar and the assembly Ibar each with twoA pins rigidly attached thereto and standing at right angles thereto on either of which loose leaf sheets that have been suitably perforated can be assembled.

Another object of the invention is to provide the hinged assembly bar with a tube standing perpendicularly thereto and rigidly attached thereto which tube serves as a pin of large diameter for the purpose of engaging with the large perforation in each sheet.

Another object of the invention is to provide a backV made with two pieces to one of which the covers are hinged and an auxiliary back having al flange rigid therewith on one side and a ange hinged thereto on the other side, the hinged iiange having the two pins of small diameter and the tube attached thereto at right angles to the flange.

Another object of the invention is to provide a small opening in the rigid locking ange and in the loose detachable assembly bar which openings When the binder is closed or the book is shut stand in line with the opening of the tube.

Another object of the invention is to provide a separate loose pin that passes through the small opening in the rigid flange and then through the opening in the detachable assembly bar and into the tube for the purpose ofA locking the rigid ilange on one side of the auxiliary back in a position parallel to the hinged flange on the other side of the back thereby locking the loose sheets in the binder.

Another object of the invention is to hold the loose pin tightly in place by one of the covers when the book is closed.

These and other objects of the invention will be illustrated in the drawings described in the speciiication and pointed out in the claims at the end thereof.

In the drawings:

Figure 1 is assembly view of the `binder with all the parts thereof in place and with one of the covers shown in open position, the loose leaf sheets being omitted therefrom.

Figure 2 is a front elevation of the lbinder with the covers in closed position looking at it from the right in Figure 1, the parts being shown on a larger scale than Figure 1.

Figure k3 is a section on the line 33e- 3x in Figure 2.

Figure 4 is an assembly view of` the binder with the two covers and the .back all shown'in the same plane and with the loose detachable assembly bar removed with part of the loosesheets assembled thereon, another part of the loose Vsheets being left assembled on the hinged assembly bar.

Figure 5 is a sectional view through the back of the binder on the line ytix- #532 of Figure -2, showing the tube in section with the locking pin inserted therein, it being understood that Figures 2, 3 and 5 are all in the same scale and are shown on a scale larger than Figures 1 and 4.

In the drawings, like reference niunerals indicate like parts.

In the drawings referencenumerall l indicates the back of the binder to which are hinged the covers 2 and 3.

Reference'numeral 4 indicates the secondary back which has the flange `5 rigid therewith on the oneV side andthe assembly bar orvange 6 hinged thereto on the other side. The flange is separate from the ycover y2v so that the cover 2 can swing'independent thereof'.`v t

Rigidly attachedY to the hinged flange or assembly bar 6 are the pins .1 and 8 near the outer ends thereof and the tube 9 at the middle thereof. These parts '1,8 and 9 stand perpendicular to the hinged assemmy bar s. The rigid aange 5 has one'hole l0 therein which hole is substantially the same diameter as the inside diameter onthe'tubeS. M l' I I Loosely associated with the rigid flange 5 is the loose detachable assembly bar Il shown in Figure (i in whichlbar is provided three holes l 2,. i3 and 14'.,` the hole I3 being in alignment' with the hole I0 in the flange 5 andthehole inthe tube 9 when the parts are assembled as shown in Figure 1, and the holesl2 and Mare in line and also engage with the pins 'l and 8 when the partsv are assembled as shown in Figure'l. 'Y

On the loose assembly bar Il is provided two pins l5 and lliv rigid therevvtihV which" pins are shown in full lines in Figure 2 and in dotted lines in Figure 4. When thebook is assembled com-v plete as shown in Figure 1, the pins 'l and 8 ex-v tend up through the loosevleaves and the pins Figure 1 whether the book is full of leaves or only partially full of leaves.

The leaves are assembled in the book in the first instance as shown by opening the book as in Figure 4. and then placing the leaves in their proper order on the pins 'l and 8 and the tube -9 when all the leaves are placed on the pins 1 and 8 in the first instance then the loose assembly bar il is placed in proper position with its pins l5 and I6 inserted in the perforations in the leaves, then the back l and 4 is swung from the position shown in Figure 4 to the position shown in Figure 1. This brings the rigid vlocking flange 5 into position over the loose assembly bar Il and then the locking pin i1 is in- Y serted through the holes l and i3 and :into the hole in the tube 9, this completes the locking of all the parts together and vthe assembly of all the parts is complete, and the cover 2 can be swung into place to close the book as shown in Figure 5.

When it is necessary to open vthe binder for the purpose of removing some sheets or inserting additional sheets, the process of the assembly as above described is reversed as follows:

The cover 2 is swung back to the position shown in Figure 1. The locking pin I1 is removed, the rigid locking flange is swung back to the position shown in Figure 4 and the loose assembly bar Il is removed and all the sheets that are temporarily to be removed are removed with it while in engagement therewith. This exposes the sheet or sheets that it is desired to be removed which sheet or sheets can then be taken out and others can be inserted in their place and this insertion and removal of sheets can be followed up indefinitely until all the sheets are assembled as may be desired on either the hinged assembly bar 6 or on the loose assembly bar' Il. Then the 'two parts of the book can be brought together so that the pins l5 and I5 engage with the holes I9 and 2l] and the pins 1 and 8 engage with the holes 2i and 22 in the loose sheets and the tube 9 engages with the vlarge hole 23 in the loose sheets after which the two parts are fastened together by raising the back to the position shown in Figure 1 and bringing the flange 5 into line and inserting vthe locking pin l1. Then the cover 2 can be thrown to closed position.

It will also be understood that in making the binder in this way all metal parts can be entirely dispensed with or such parts as may be desired may be made of metal. In the preferred construction the parts 1, 8, I5, I6 and l1 and the tube 9 are made of ber. The bars 6 and Il can be of fiber or wood. It being understood that ber parts are used instead of metal because of priority orders, and it will also be understood that other materials may be substituted for the parts made of fiber.
